Zum Wired App Mode vs CNET Decision Guide

Last modified by Craig Lewis on 2026/04/08 20:33

Zum wired can be deployed in App (Zum) Mode or CNET Mode. App mode will perform lighting control logic within the Zum JBOX hardware while CNET mode pushes all logic back to the Control System. ShowRunnerCLC™ supports both modes and can be used to enhance app mode or allow complete control over the hardware to perform functionality. All hardware does not need to be in app mode on a project. You can mix and match as needed. This is not an exhaustive list but serves as a guide for when Zum is required to be in CNET mode to achieve the desired functionality.

Due to technical complexities with firmware, Zum AutoSwitch is not recommended. Either provision entirely in Zum App Mode or CNET Mode.

Notes

1 - [App Mode Only] Logic must be handled by ShowRunnerCLC™. An active connection to the control system/ShowRunnerCLC™ is required.
2 - [App Mode Only] Some logic may be handled by ShowRunnerCLC™ depending on active setting. An active connection to the control system/ShowRunnerCLC™ will be required if handled by ShowRunnerCLC™.
3 - [App Mode Only] Keypad Required
4 - [App Mode Only] 3 settings, On/Off and All Scenes Only, configured per load, max of 30 seconds
